Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q4 i? Variance in child-level effect sizes was significantly related to in-service effects on quality ratings, with 53% explained variance; no standardized effect size is printed for this relation. → F. Egert 2018
Evidence¶
F. Egert 2018¶
F. Egert, R.G. Fukkink, A.G. Eckhardt. (2018). Impact of In-Service Professional Development Programs for Early Childhood Teachers on Quality Ratings and Child Outcomes: A Meta-Analysis. Review of Educational Research. https://doi.org/10.3102/0034654317751918
q4 · i? · quant-synthesis · r?
Meta-analytic moderator analysis across the subset of studies with child-level outcomes. The review reports that "Variance in effect sizes at child level was significantly related to in-service effects on quality ratings (53% explained variance)"; no standardized effect size is printed for this relation, so impact is null.
"Variance in effect sizes at child level was significantly related to in-service effects on quality ratings (53% explained variance)."
Discussion¶
Related Claims¶
- In the same subset, in-service PD shows a medium effect at the corresponding classroom level (ES = 0.45) — related
- In-service professional development for ECEC teachers produces a medium improvement in externally rated process quality (ES = 0.68) — related
- In-service PD shows a small effect on child development (ES = 0.14) in studies reporting both quality and child outcomes — related
